Abstract

La présente invention concerne un procédé et un dispositif d'émission d'un signal de référence. Le procédé consiste : à acquérir une vitesse de déplacement actuelle; à déterminer une densité d'émission de signal de référence correspondante selon un niveau de vitesse auquel la vitesse de déplacement actuelle appartient; et à émettre un signal de référence vers un terminal monté sur véhicule d'extrémité opposée connectée selon la densité d'émission de signal de référence.
